Things might be getting a little more difficult for the James Bonds and Jason Bournes of the world. A new system developed by Prof. Uwe Hartmann at Germany’s Saarland University utilizes the Earth’s magnetic fields to instantly determine when and where a security fence has been breached.

The technology is known as the Vibromag Cable, and incorporates a long cable containing regularly-spaced magnetometer probes. That cable is permanently or temporarily added to an existing metal fence, or it can be buried in the ground underneath one. . . . Read Complete Report

Scientists have discovered a layer of liquified molten rock in Earth’s mantle that may be responsible for the sliding motions of the planet’s massive tectonic plates. The finding may carry far-reaching implications, from understanding basic geologic functions of the planet to new insights into volcanism and earthquakes.

The research was funded by the National Science Foundation (NSF), and is reported in this week’s issue of the journal Nature by Samer Naif, Kerry Key, and Steven Constable of the Scripps Institution of Oceanography (SIO), and Rob Evans of the Woods Hole Oceanographic Institution. . . .

Oceanography Student Uses Crashing Waves On Shorelines to Study Earth’s Interior

December 12, 2012 / dgcrenshaw / No comments

from Science Daily

Dec. 5, 2012 — Scientists have long used the speed of seismic waves traveling through Earth as a means of learning about the geologic structure beneath Earth’s surface, but the seismic waves they use have typically been generated by earthquakes or human-made explosions. A University of Rhode Island graduate student is using the tiny seismic waves created by ocean waves crashing on shorelines around the world to learn how an underwater plateau was formed 122 million years ago. . . .

New camera provides tantalizing clues of new atmospheric phenomenon

WASHINGTON, Nov. 29, 2012—Hoping to expand our understanding of auroras and other fleeting atmospheric events, a team of space-weather researchers designed and built NORUSCA II, a new camera with unprecedented capabilities that can simultaneously image multiple spectral bands, in essence different wavelengths or colors, of light. The camera was tested at the Kjell Henriksen Observatory (KHO) in Svalbard, Norway, where it produced the first-ever hyperspectral images of auroras—commonly referred to as “the Northern (or Southern) Lights”—and may already have revealed a previously unknown atmospheric phenomenon.

Details on the camera and the results from its first images were published today in the Optical Society’s (OSA) open-access journal Optics Express. . . . Read Complete Report

Annual to decadal changes in the earth’s magnetic field in a region that stretches from the Atlantic to the Indian Ocean have a close relationship with variations of gravity in this area. From this it can be concluded that outer core processes are reflected in gravity data. This is the result presented by a German-French group of geophysicists in the latest issue of PNAS (Proceedings of the National Academy of Sciences of the United States). . . . Read Complete Report
